Hi,
FYI, your patch has been queued to stable release 20.11.2
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. So please
shout if anyone has objections.
Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.
Queued patches are on a temporary branch at:
https://github.com/steevenlee/dpdk
This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/20bbce05a8fdf7592da64bd30bc8575d931c7aff
Thanks.

[ upstream commit b7fe612ac1de393f869c9818d5503633c8e96b36 ]
Fix typos in the names of kernel drivers based on UIO,
and make sure the generic term for the interface is UIO in capitals.
Fixes: 3a78b2f73206 ("doc: add virtio crypto PMD guide")
Fixes: 3cc4d996fa75 ("doc: update VFIO usage in qat crypto guide")
Fixes: 39922c470e3c ("doc: add known uio_pci_generic issue for i40e")
Fixes: 86fa6c57a175 ("doc: add known igb_uio issue for i40e")
Fixes: beff6d8e8e2e ("net/netvsc: add documentation")
